Abstract
a-Aminoxy acid conjugates and hybrid a-aminoxy
dipeptide conjugates showing blue to green fluorescence (with quantum yields 0.23–0.71) were synthesized (75–92% yield) from N-Acylbenzotriazoles. 7-Methoxycoumarin derivatives were obtained(quantum yields j 0.35–0.71) that could be suitable for peptide
assays. The wavelengths of the absorption maxima (lAbs) and
the fluorescence emission maxima (lEm) and the quantum yields (j)
of some coumarin-3-ylcarbonyl aminoxy acid conjugates were
comparable to those of the analogous amino acid derivatives.
